Safety regulations require the following during a repair:
•Connect the set to the Mains/AC Power via an isolation
transformer (> 800 VA).
•Replace safety components, indicated by the symbol h,
only by components identical to the original ones. Any
other component substitution (other than original type) may
increase risk of fire or electrical shock hazard.
Safety regulations require that after a repair, the set must be
returned in its original condition. Pay in particular attention to
the following points:
•Route the wire trees correctly and fix them with the
mounted cable clamps.
•Check the insulation of the Mains/AC Power lead for
external damage.
•Check the strain relief of the Mains/AC Power cord for
proper function.
•Check the electrical DC resistance between the Mains/AC
Power plug and the secondary side (only for sets that have
a Mains/AC Power isolated power supply):
1. Unplug the Mains/AC Power cord and connect a wire
between the two pins of the Mains/AC Power plug.
2. Set the Mains/AC Power switch to the “on” position
(keep the Mains/AC Power cord unplugged!).
3. Measure the resistance value between the pins of the
Mains/AC Power plug and the metal shielding of the
tuner or the aerial connection on the set. The reading
should be between 4.5 Mohm and 12 Mohm.
4. Switch “off” the set, and remove the wire between the
two pins of the Mains/AC Power plug.
•Check the cabinet for defects, to prevent touching of any
inner parts by the customer.
2.2Warnings
•All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD w). Careless handling
during repair can reduce life drastically. Make sure that,
during repair, you are connected with the same potential as
the mass of the set by a wristband with resistance. Keep
components and tools also at this same potential.
•Be careful during measurements in the high voltage
section.
•Never replace modules or other components while the unit
is switched “on”.
•When you align the set, use plastic rather than metal tools.
This will prevent any short circuits and the danger of a
circuit becoming unstable.
2.3Notes
2.3.1 General
•Measure the voltages and waveforms with regard to the
chassis (= tuner) ground (H), or hot ground (I), depending
on the tested area of circuitry. The voltages and waveforms
shown in the diagrams are indicative. Measure them in the
Service Default Mode (see chapter 5) with a colour bar
signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated
otherwise) and picture carrier at 475.25 MHz for PAL, or
61.25 MHz for NTSC (channel 3).
•Where necessary, measure the waveforms and voltages
with (D) and without (E) aerial signal. Measure the
voltages in the power supply section both in normal
operation (G) and in stand-by (F). These values are
indicated by means of the appropriate symbols.
•Manufactured under license from Dolby Laboratories.
“Dolby”, “Pro Logic” and the “double-D symbol”, are
trademarks of Dolby Laboratories.
2.3.2Schematic Notes
•All resistor values are in ohms, and the value multiplier is
often used to indicate the decimal point location (e.g. 2K2
indicates 2.2 kohm).
•Resistor values with no multiplier may be indicated with
either an “E” or an “R” (e.g. 220E or 220R indicates 220
ohm).
•All capacitor values are given in micro-farads (μ= × 10
nano-farads (n= × 10
•Capacitor values may also use the value multiplier as the
decimal point indication (e.g. 2p2 indicates 2.2 pF).
•An “asterisk” (*) indicates component usage varies. Refer
to the diversity tables for the correct values.
•The correct component values are listed in the Spare Parts
List. Therefore, always check this list when there is any
doubt.
2.3.3BGA (Ball Grid Array) ICs
Introduction
For more information on how to handle BGA devices, visit this
URL: www.atyourservice.ce.philips.com (needs subscription,
not available for all regions). After log-in, select “Magazine”,
then go to “Repair downloads”. Here you will find Information
on how to deal with BGA-ICs.
BGA Temperature Profiles
For BGA-ICs, you must use the correct temperature-profile,
which is coupled to the 12NC. For an overview of these profiles,
visit the website www.atyourservice.ce.philips.com (needs
subscription, but is not available for all regions)
You will find this and more technical information within the
“Magazine”, chapter “Repair downloads”.
For additional questions please contact your local repair help
desk.
2.3.4Lead-free Soldering
Due to lead-free technology some rules have to be respected
by the workshop during a repair:
•Use only lead-free soldering tin Philips SAC305 with order
code 0622 149 00106. If lead-free solder paste is required,
please contact the manufacturer of your soldering
equipment. In general, use of solder paste within
workshops should be avoided because paste is not easy to
store and to handle.
•Use only adequate solder tools applicable for lead-free
soldering tin. The solder tool must be able:
– To reach a solder-tip temperature of at least 400°C.
– To stabilize the adjusted temperature at the solder-tip.
– To exchange solder-tips for different applications.
•Adjust your solder tool so that a temperature of around
360°C - 380°C is reached and stabilized at the solder joint.
Heating time of the solder-joint should not exceed ~ 4 sec.
Avoid temperatures above 400°C, otherwise wear-out of
tips will increase drastically and flux-fluid will be destroyed.
To avoid wear-out of tips, switch “off” unused equipment or
reduce heat.
•Mix of lead-free soldering tin/parts with leaded soldering
tin/parts is possible but PHILIPS recommends strongly to
-9
), or pico-farads (p= × 10
-12
-6
),
).
avoid mixed regimes. If this cannot be avoided, carefully
clear the solder-joint from old tin and re-solder with new tin.
2.3.5 Alternative BOM identification
The third digit in the serial number (example:
AG2B0335000001) indicates the number of the alternative
B.O.M. (Bill Of Materials) that has been used for producing the
specific TV set. In general, it is possible that the same TV
model on the market is produced with e.g. two different types
of displays, coming from two different suppliers. This will then
result in sets which have the same CTN (Commercial Type
Number; e.g. 28PW9515/12) but which have a different B.O.M.
number.
By looking at the third digit of the serial number, one can
identify which B.O.M. is used for the TV set he is working with.
If the third digit of the serial number contains the number “1”
(example: AG1B033500001), then the TV set has been
manufactured according to B.O.M. number 1. If the third digit is
a “2” (example: AG2B0335000001), then the set has been
produced according to B.O.M. no. 2. This is important for
ordering the correct spare parts!
For the third digit, the numbers 1...9 and the characters A...Z
can be used, so in total: 9 plus 26= 35 different B.O.M.s can be
indicated by the third digit of the serial number.
Identification: The bottom line of a type plate gives a 14-digit
serial number. Digits 1 and 2 refer to the production centre (e.g.
AG is Bruges), digit 3 refers to the B.O.M. code, digit 4 refers
to the Service version change code, digits 5 and 6 refer to the
production year, and digits 7 and 8 refer to production week (in
example below it is 2006 week 17). The 6 last digits contain the
serial number.

2.3.6Board Level Repair (BLR) or Component Level Repair
(CLR)
If a board is defective, consult your repair procedure to decide
if the board has to be exchanged or if it should be repaired on
component level.
If your repair procedure says the board should be exchanged
completely, do not solder on the defective board. Otherwise, it
cannot be returned to the O.E.M. supplier for back charging!
2.3.7Practical Service Precautions
•It makes sense to avoid exposure to electrical shock.
While some sources are expected to have a possible
dangerous impact, others of quite high potential are of
limited current and are sometimes held in less regard.
•Always respect voltages. While some may not be
dangerous in themselves, they can cause unexpected
reactions that are best avoided. Before reaching into a
powered TV set, it is best to test the high voltage insulation.
It is easy to do, and is a good service precaution.

Figure 4-4 Cable dressing 47" sets
The foam bars (order code 3122 785 90580 for two pieces) can
be used for all types and sizes of Flat TVs. See figure “Foam
bars” for details. Sets with a display of 42" and larger, require
four foam bars [1]. Ensure that the foam bars are always
supporting the cabinet and never only the display.
Caution: Failure to follow these guidelines can seriously
damage the display!
By laying the TV face down on the (ESD protective) foam bars,
a stable situation is created to perform measurements and
alignments. By placing a mirror under the TV, you can monitor
the screen.

5.1Test Points
As most signals are digital, it will be difficult to measure
waveforms with a standard oscilloscope. However, several key
ICs are capable of generating test patterns, which can be
controlled via ComPair. In this way it is possible to determine
which part is defective.
Perform measurements under the following conditions:
•Service Default Mode.
•Video: Colour bar signal.
•Audio: 3 kHz left, 1 kHz right.
5.2Service Modes
Service Default mode (SDM) and Service Alignment Mode
(SAM) offers several features for the service technician, while
the Customer Service Mode (CSM) is used for communication
between the call centre and the customer.
This chassis also offers the option of using ComPair, a
hardware interface between a computer and the TV chassis. It
offers the abilities of structured troubleshooting, error code
reading, and software version read-out for all chassis.
(see also paragraph “ComPair”).
– Picture mute (blue mute or black mute).
– Automatic volume levelling (AVL).
– Skip/blank of non-favourite pre-sets.
How to Activate SDM
For this chassis there are two kinds of SDM: an analogue SDM
and a digital SDM. Tuning will happen according table “SDM
Default Settings”.
•AnalogueSDM: use the standard RC-transmitter and key
in the code “062596”, directly followed by the “MENU”
button.
Note: It is possible that, together with the SDM, the main
menu will appear. To switch it “off”, push the “MENU”
button again.
•DigitalSDM: use the standard RC-transmitter and key in
the code “062593”, directly followed by the “MENU” button.
Note: It is possible that, together with the SDM, the main
menu will appear. To switch it “off”, push the “MENU”
button again.
•AnalogueSDM can also be activated by shorting for a
moment the two solder pads [1] (see figure “Service mode
pads”) on the SSB, with the indication “SDM”. Activation
can be performed in all modes, except when the set has a
problem with the Stand-by Processor.

5.2.1Service Default Mode (SDM)
Purpose
•To create a pre-defined setting, to get the same
measurement results as given in this manual.
•To override SW protections detected by stand-by
processor and make the TV start up to the step just before
protection (a sort of automatic stepwise start up). See
paragraph “Stepwise Start Up”.
•To override SW protections detected by MIPS. See also
paragraph “Error codes”.
•To start the blinking LED procedure (not valid for
protections detected by standby software).

•All picture settings at 50% (brightness, colour, contrast).
After activating this mode, “SDM” will appear in the upper right
corner of the screen (if you have picture).
How to Navigate
When you press the “MENU” button on the RC transmitter, the
set will toggle between the SDM and the normal user menu
(with the SDM mode still active in the background).
How to Exit SDM
Use one of the following methods:
•Switch the set to STAND-BY via the RC-transmitter.
•Via a standard customer RC-transmitter: key in “00”sequence.
5.2.2Service Alignment Mode (SAM)
Purpose
•To perform (software) alignments.
•To change option settings.
•To easily identify the used software version.
•To view operation hours.
•To display (or clear) the error code buffer.

Service Modes, Error Codes, and Fault Finding
How to Activate SAM
Via a standard RC transmitter: key in the code “062596”
directly followed by the “INFO” button. After activating SAM
with this method a service warning will appear on the screen,
you can continue by pressing the red button on the RC.
Contents of SAM:
•Hardware Info.
– A. SW Version. Displays the software version of the
main software (example: Q581E-1.2.3.4 =
AAAAB_X.Y.W.Z).
•AAAA= the chassis name.
•B= the region: A= AP, E= EU, L= LatAm, U = US.
For AP sets it is possible that the Europe software
version is used.
•X.Y.W.Z= the software version, where X is the
main version number (different numbers are not
compatible with one another) and Y.W.Z is the sub
version number (a higher number is always
compatible with a lower number).
– B. SBY PROC Version. Displays the software version
of the stand-by processor.
– C. Production Code. Displays the production code of
the TV, this is the serial number as printed on the back
of the TV set. Note that if an NVM is replaced or is
initialized after corruption, this production code has to
be re-written to NVM. ComPair will foresee in a
possibility to do this.
•Operation Hours. Displays the accumulated total of
operation hours (not the stand-by hours). Every time the
TV is switched “on/off”, 0.5 hours is added to this number.
•Errors (followed by maximal 10 errors). The most recent
error is displayed at the upper left (for an error explanation
see paragraph “Error Codes”).
•Reset Error Buffer. When you press “cursor right” (or the
“OK button) and then the “OK” button, the error buffer is
reset.
•Alignments. This will activate the “ALIGNMENTS” submenu.
•Dealer Options. Extra features for the dealers.
•Options. Extra features for Service. For more info
regarding option codes, see chapter 8 “Alignments”.
Note that if you change the option code numbers, you have
to confirm your changes with the “OK” button before you
store the options. Otherwise you will loose your changes.
•Initialize NVM. The moment the processor recognizes a
corrupted NVM, the “initialize NVM” line will be highlighted.
Now, you can do two things (dependent of the service
instructions at that moment):
– Save the content of the NVM via ComPair for
development analysis, before initializing. This will give
the Service department an extra possibility for
diagnosis (e.g. when Development asks for this).
– Initialize the NVM.
Note: When you have a corrupted NVM, or you have replaced
the NVM, there is a high possibility that you will not have picture
anymore because your display code is not correct. So, before
you can initialize your NVM via the SAM, you need to have a
picture and therefore you need the correct display option. Refer
to chapter 8 for details. To adapt this option, you can use
ComPair (the correct HEX values for the options can be found
in chapter 8 “Alignments”) or a method via a standard RC
(described below).
Changing the display option via a standard RC: Key in the
code “062598” directly followed by the “MENU” button and
“XXX”, where XXX is the 3 digit decimal display code (see table
“Option code overview” in chapter 8 “Alignments”, or sticker on
the side/bottom of the cabinet). Make sure to key in all three
digits, also the leading zero’s. If the above action is successful,
the front LED will go out as an indication that the RC sequence
was correct. After the display option is changed in the NVM, the
TV will go to the Stand-by mode. If the NVM was corrupted or
empty before this action, it will be initialized first (loaded with
default values). This initializing can take up to 20 seconds.

•Store. All options and alignments are stored when
pressing “cursor right” (or the “OK” button) and then the
“OK”-button.
•SW Maintenance.
– SW Events. Not useful for Service purposes. In case
of specific software problems, the development
department can ask for this info.
– HW Events. Not useful for Service purposes. In case
of specific software problems, the development
department can ask for this info.
•Test settings. For development purposes only.
•Upload to USB. To upload several settings from the TV to
a USB stick, which is connected to the Side I/O. The items
are “Channel list”, “Personal settings”, “Option codes”,
“Display-related alignments” and “History list”. First you
have to create a directory “repair” in the root of the USB
stick.To upload the settings you have to select each item
separately, press “cursor right” (or the “OK button), confirm
with “OK” and wait until “Done” appears. In case the
download to the USB stick was not successful “Failure” will
appear. In this case, check if the USB stick is connected
properly and if the directory “repair” is present in the root of
the USB stick. Now the settings are stored onto your USB
stick and can be used to download onto another TV or
other SSB. Uploading is of course only possible if the
software is running and if you have a picture. This method
is created to be able to save the customer’s TV settings
and to store them into another SSB.
•Download from USB. To download several settings from
the USB stick to the TV. Same way of working as with
uploading. To make sure that the download of the channel
list from USB to the TV is executed properly, it is necessary
to restart the TV and tune to a valid preset if necessary.
Note: The “History list item” can not be downloaded from
USB to the TV. This is a “read-only” item. In case of specific
problems, the development department can ask for this
info.
How to Navigate
•In SAM, you can select the menu items with the “CURSOR
UP/DOWN” key on the RC-transmitter. The selected item
will be highlighted. When not all menu items fit on the
screen, move the “CURSOR UP/DOWN” key to display the
next/previous menu items.
•With the “CURSOR LEFT/RIGHT” keys, it is possible to:
– (De) activate the selected menu item.
– (De) activate the selected sub menu.
•With the “OK” key, it is possible to activate the selected
action.
How to Exit SAM
Use one of the following methods:
•Press the “MENU” button on the RC-transmitter.
Service Modes, Error Codes, and Fault Finding
EN 27Q528.1A LA5.
•Switch the set to STAND-BY via the RC-transmitter.
5.2.3 Customer Service Mode (CSM)
Purpose
When a customer is having problems with his TV-set, he can
call his dealer or the Customer Helpdesk. The service
technician can then ask the customer to activate the CSM, in
order to identify the status of the set. Now, the service
technician can judge the severity of the complaint. In many
cases, he can advise the customer how to solve the problem,
or he can decide if it is necessary to visit the customer.
The CSM is a read only mode; therefore, modifications in this
mode are not possible.
When in this chassis CSM is activated, a colour bar test pattern
will be visible for 5 seconds. This test pattern is generated by
the Pacific3. So if you see this test pattern you can determine
that the back end video chain (Pacific3, LVDS, and display) of
the SSB is working. In case of a set with DFI panel, an extra
test picture is generated. So you will see the Pacific3 test
picture for 3 seconds and then the DFI EPLD test picture for
another 3 seconds. With this extra test picture you can
determine if the DFI board is working properly.
Also new in this chassis: when you activate CSM and there is
a USB stick connected to the TV, the software will dump the
complete CSM content to the USB stick. The file (Csm.txt) will
be saved in the root of your USB stick. This info can be handy
if you do not have picture.
Another new item in this chassis is when CSM is activated, the
complete error-buffer content will be shown via the blinking
LED procedure.
How to Activate CSM
Key in the code “123654” via the standard RC transmitter.
Note: Activation of the CSM is only possible if there is no (user)
menu on the screen!
How to Navigate
By means of the “CURSOR-DOWN/UP” knob on the RCtransmitter, you can navigate through the menus.
Contents of CSM
•Set Type. This information is very helpful for a helpdesk/
workshop as reference for further diagnosis. In this way, it
is not necessary for the customer to look at the rear of the
TV-set. Note that if an NVM is replaced or is initialized after
corruption, this set type has to be re-written to NVM.
ComPair will foresee in a possibility to do this.
•Production Code. Displays the production code (the serial
number) of the TV. Note that if an NVM is replaced or is
initialized after corruption, this production code has to be
re-written to NVM. ComPair will foresee a in possibility to
do this.
•Code 1. Gives the last five errors of the error buffer. As
soon as the built-in diagnose software has detected an
error, the buffer is adapted. The last occurred error is
displayed on the leftmost position. Each error code is
displayed as a 2-digit number. When less than 10 errors
occur, the rest of the buffer is empty (00). See also
paragraph “Error Codes” for a description.
•Code 2. Gives the first five errors of the error buffer. See
also paragraph “Error Codes” for a description.
•Options 1. Gives the option codes of option group 1 as set
in SAM (Service Alignment Mode).
•Options 2. Gives the option codes of option group 2 as set
in SAM (Service Alignment Mode).
•12NC SSB. Gives an identification of the SSB as stored in
NVM. Note that if an NVM is replaced or is initialized after
corruption, this identification number has to be re-written to
NVM. ComPair will foresee in a possibility to do this. This
identification number consists of 14 characters and is built
up as follows:
- Seven last characters of the 12NC of the SSB itself.
- the serial number of the SSB, which consists of seven
digits. Both can be found on a sticker on the PWB of the
SSB itself. The format of the identification number is then
as follows: <last seven characters of 12NC of SSB><serial
number of SSB> (total fourteen characters).
•Installed date. Indicates the date of the first installation of
the TV. This date is acquired via time extraction.
•Digital Natural Motion. Gives the status of the Digital

There are two possible situations: one for protections detected
by the stand-by software and one for protections detected by
the main software.
When the TV is in a protection state due to an error detected by
stand-by software (and thus blinking an error) and SDM is
activated via short-circuiting the pins on the SSB, the TV starts
up until it reaches the situation just before protection. So, this
is a kind of automatic stepwise start-up. In combination with the
start-up diagrams below, you can see which supplies are
present at a certain moment. Important to know is, that if e.g.
the 3V3 detection fails (and thus error 8 is blinking) and the TV
is restarted via SDM, the Stand-by Processor will enable the
3V3, but will not go to protection now. The TV will stay in this
situation until it is reset (Mains/AC Power supply interrupted).
Caution: in case the start up in this mode with a faulty FET
7U01 is done, you can destroy all IC’s supplied by the +3V3,
Mains

on
due to overvoltage. It is recommended to measure first the FET
7U01 on short-circuit before activating SDM via the service
pads.
When the TV is in protection state due to an error detected by
main software (MIPS protection) and SDM is activated via
short-cutting the service pads on the SSB, the TV starts up and
ignores the error.
In this chassis, only error “63” (power-ok) is a MIPS protection
and already displays the failure via blinking LED.
The abbreviations “SP” and “MP” in the figures stand for:
•SP: protection or error detected by the Stand-by Processor.
•MP: protection or error detected by the MIPS Main Processor.

5.4Service Tools
5.4.1 ComPair
Introduction
ComPair (Computer Aided Repair) is a Service tool for Philips
Consumer Electronics products. and offers the following:
1. ComPair helps you to quickly get an understanding on how
to repair the chassis in a short and effective way.
2. ComPair allows very detailed diagnostics and is therefore
capable of accurately indicating problem areas. You do not
have to know anything about I
yourself, because ComPair takes care of this.
3. ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the uP
is working) and all repair information is directly available.
4. ComPair features TV software up possibilities.
Specifications
ComPair consists of a Windows based fault finding program
and an interface box between PC and the (defective) product.
The (new) ComPair II interface box is connected to the PC via
an USB cable. For the TV chassis, the ComPair interface box
and the TV communicate via a bi-directional cable via the
service connector(s).

5.5Error Codes
5.5.1Introduction
The error code buffer contains all detected errors since the last
time the buffer was erased. The buffer is written from left to
right, new errors are logged at the left side, and all other errors
shift one position to the right.
When an error occurs, it is added to the list of errors, provided
the list is not full. When an error occurs and the error buffer is
full, then the new error is not added, and the error buffer stays
intact (history is maintained).
To prevent that an occasional error stays in the list forever, the
error is removed from the list after more than 50 hrs. of
operation.
When multiple errors occur (errors occurred within a short time
span), there is a high probability that there is some relation
between them.
Basically there are three kinds of errors:
•Errors detected by the Stand-by software. These errors
will always lead to protection and an automatic start of the
blinking LED for the concerned error (see paragraph “The
Blinking LED Procedure”). In these cases SDM can be
used to start up (see chapter “Stepwise Start-up”). Note
that it can take up to 90 seconds before the TV goes to
protection and starts blinking the error (e.g. error 53)
•Errors detected by main software that lead to protection. In this case the TV will go to protection and the
front LED should also blink the concerned error. See also
paragraph “Error Codes” -> “Error Buffer” -> “Extra Info”.
For this chassis only error 63 is a protection error detected
by main software.
•Errors detected by main software that do not lead to protection. In this case the error will be logged into the
error buffer and can be read out via ComPair, via blinking
LED method, or in case you have picture, via SAM.
5.5.2How to Read the Error Buffer
Use one of the following methods:
•On screen via the SAM (only if you have a picture). E.g.:
– 00 00 00 00 00: No errors detected
– 06 00 00 00 00: Error code 6 is the last and only
detected error
– 09 06 00 00 00: Error code 6 was first detected and
error code 9 is the last detected error
•Via the blinking LED procedure (when you have no
picture). See next paragraph.
•Via ComPair.
•Via CSM. when CSM is activated the blinking LED
procedure will start and the CSM content will be written to
a USB stick (if present).
5.5.3How to Clear the Error Buffer
Use one of the following methods:
•By activation of the “RESET ERROR BUFFER” command
in the SAM menu.
•With a normal RC, key in sequence “MUTE” followed by
“062599” and “OK”.
•If the content of the error buffer has not changed for 50+
hours, it resets automatically.
EN 40Q528.1A LA5.
Service Modes, Error Codes, and Fault Finding
5.5.4 Error Buffer
In case of non-intermittent faults, clear the error buffer before
you begin the repair (before clearing the buffer, write down the
content, as this history can give you significant information).
This to ensure that old error codes are no longer present.
If possible, check the entire contents of the error buffer. In
some situations, an error code is only the result of another error
code and not the actual cause (e.g., a fault in the protection
detection circuitry can also lead to a protection).
There are several mechanisms of error detection:
•Via error bits in the status registers of ICs.
•Via polling on I/O pins going to the stand-by processor.
•Via sensing of analogue values on the stand-by processor
or the PNX85xx.
•Via a “not acknowledge” of an I
2
C communication.
Take notice that some errors need more than 90 seconds
before they start blinking or before they will be logged. So in
case of problems wait 2 minutes from start-up onwards, and
then check if the front LED is blinking or if an error is logged.

Extra Info
•Rebooting. When a TV is constantly rebooting due to
internal problems, most of the time no errors will be logged
or blinked. This rebooting can be recognized via a ComPair
interface and Hyperterminal (for Hyperterminal settings,
see paragraph “Stand-by software upgrade). You will see
that the loggings which are generated by the main software
keep continuing. In this case (rebooting) diagnose has to
be done via ComPair.
•Error 3 (I

manual, this error was not working as expected (error 3 is
logged and can be read out). Current situation: when this

use ComPair (e.g. read out the NVM content). Instead of
error “3” it is possible you will see error “2” in the error
buffer.
•Error 5 (PNX85xx doesn’t boot). Indicates that the main
processor was not able to read his bootscript. This error will
point to a hardware problem around the PNX85xx (supplies
not OK, PNX 8535 completely dead, I
and Stand-by Processor broken, etc...). When error 5

•Error 24 (I

possible that error 47(no existing error) will also be logged.
•Error 28 (DFI Ambilight MOP). It can take up to 2 minutes
or more before this error is logged. So if you suspect that
this MOP is defective: clear the error buffer, restart the TV
and wait for about 2 minutes before checking the error
buffer.
•Error 37 (Channel decoder). When this error occurs,
there probably will be no picture and sound from tuner
input. As a side effect of error 37 it is possible that error 4
(no existing error) is also logged.
•Error 46 (Pacific 3). When there is an actual problem with
or around the Pacific during start-up, you will have no
picture and error 46 will be blinked via the blinking LED
procedure. For further diagnosis you can always dump the
CSM content on USB stick (see CSM) or use ComPair.
•Error 53. This error will indicate that the PNX85xx has read
his bootscript (if this would have failed, error 5 would blink)
but initialization was never completed because of hardware
problems (NAND flash, ...) or software initialization
problems. Possible cause could be that there is no valid
software loaded (try to upgrade to the latest main software
version). Note that it can take up to 2 minutes before the TV
starts blinking error 53.
•Error 63 (POWER OK). When this error occurs, it means
that the POWER-OK line did not became “high”. This error
is only applicable for TV’s with an LCD display. For PDP
displays there will be no protection during a POWER-OK
line failure, but error 63 will be logged in the error buffer.
Caution: in case a PDP TV ends up into power-ok
protection, it can indicate that the display option code is set
to “LCD”. To change the display option code to “PDP” you
need to activate SDM via the service pads (see figure
“Service mode pads”). Then change the display option
code blindly via a standard RC: key in the code “062598”
directly followed by the “MENU” button and “XXX” (where
XXX is the 3 digit decimal display option code as
mentioned in figure “Display option code overview”).
•Error 65 (DFI EPLD error). When this error occurs it
means that there is a problem with the I
2
C communication
towards the EPLD (picture processing EPLD, not the
Ambilight EPLD) on the DFI panel.

EN 41Q528.1A LA5.
5.6The Blinking LED Procedure
5.6.1 Introduction
The blinking LED procedure can be split up into two situations:
•Blinking LED procedure in case of a protection. In this case
the error is automatically blinked. This will be only one
error, namely the one that is causing the protection.
Therefore, you do not have to do anything special, just read
out the blinks. A long blink indicates the decimal digit, a
short blink indicates the units.
•Blinking LED procedure in the “on” state. Via this
procedure, you can make the contents of the error buffer
visible via the front LED. This is especially useful for fault
finding, when there is no picture.
When the blinking LED procedure is activated in the “on” state,
the front LED will show (blink) the contents of the error-buffer.
Error-codes > 10 are shown as follows:
5. When all the error-codes are displayed, the sequence
finishes with a LED blink of 3 s,
6. The sequence starts again.
Example: Error 12 8 6 0 0.
After activation of the SDM, the front LED will show:
1. 1 long blink of 750 ms (which is an indication of the decimal
digit) followed by a pause of 1.5 s,
2. 2 short blinks of 250 ms followed by a pause of 3 s,
3. 8 short blinks followed by a pause of 3 s,
4. 6 short blinks followed by a pause of 3 s,
5. 1 long blink of 3 s to finish the sequence,
6. The sequence starts again.
5.6.2How to Activate
Use one of the following methods:
•Activate the SDM or CSM. The blinking front LED will
show the entire contents of the error buffer (this works in
“normal operation” mode).
•Transmit the commands “MUTE” - “062500” - “OK” with a normal RC. The complete error buffer is shown.
Take notice that it takes some seconds before the blinking
LED starts.
•Transmit the commands “MUTE” - “06250x” - “OK” with a normal RC (where “x” is a number between 1 and
5). When x= 1 the last detected error is shown, x= 2 the
second last error, etc.... Take notice that it takes some
seconds before the blinking LED starts.
5.7Protections
5.7.1Software Protections
Most of the protections and errors use either the stand-by
microprocessor or the MIPS controller as detection device.
Since in these cases, checking of observers, polling of ADCs,
and filtering of input values are all heavily software based,
these protections are referred to as software protections.
There are several types of software related protections, solving
a variety of fault conditions:
•Protections related to supplies: check of the 12V, +5V,
+1V2, +1V4, 2V5 and +3V3.
•Protections related to breakdown of the safety check mechanism. E.g. since the protection detections are done
by means of software, failing of the software will have to
initiate a protection mode since safety cannot be
guaranteed any more.
Remark on the Supply Errors
The detection of a supply dip or supply loss during the normal
playing of the set does not lead to a protection, but to a cold
reboot of the set. If the supply is still missing after the reboot,
the TV will go to protection.
Protections during Start-up
During TV start-up, some voltages and IC observers are
actively monitored to be able to optimise the start-up speed,
and to assure good operation of all components. If these
monitors do not respond in a defined way, this indicates a
malfunction of the system and leads to a protection. As the
observers are only used during start-up, they are described in
the start-up flow in detail (see paragraph “Stepwise Start-up”).
5.7.2Hardware Protections
The only real hardware protection in this chassis is (in case of
an audio problem) the audio protection circuit that will switch
“off” immediately the supply of the SSB. The supply will buzz
during the protection and +12VS drops to approx. 5V5 and +5V
Stand-by to approx. to 1V9. Other indication of the audio
protection is that the red LED lights up with an intensity of 50%.
Repair Tips
•It is also possible that you have an audio DC protection
because of an interruption in one or both speakers (the DC
voltage that is still on the circuit cannot disappear through
the speakers). Caution: (dis)connecting the speaker wires
during the ON state of the TV at high volume can damage
the audio amplifier.
Due to a degeneration process of the AmbiLight, it is
recommended to change both ambilight units in case one unit
needs to be repaired.
5.8.2Audio Amplifier
It is recommended to replace all components at once (7D06,
7D09, 3D01, 3D25) when a defective FET 7D10 needs to be
fixed. For the left channel (defective FET 7D35) of the audio
amplifier replace all components like 7D31, 7D34, 3D11, 3D28.
EN 42Q528.1A LA5.
Service Modes, Error Codes, and Fault Finding
5.8.3 CSM
When you activate CSM and there is a USB stick connected to
the TV, the software will dump the complete CSM content to the
USB stick. The file (Csm.txt) will be saved in the root of your
USB stick. If this mechanism works you can conclude that a
large part of the operating system is already working (MIPS,
USB...)
5.8.4DC/DC Converter
Introduction
•The best way to find a failure in the DC-DC converters is to
check their starting-up sequence at “power-on via the
mains cord”, presuming that the standby microprocessor is
operational.
•If the input voltage of DC-DC converters is around 12.7V
(measured on decoupling capacitors 2U03/2U93/2U6S
and 2U6R) and the enable signals are “low” (active) then
the output voltages should have their normal values. +12V
and +5V-POD supplies start-up first (enabled by PODMODE signal from the standby microprocessor). There is a
supplementary condition for +12V to start-up: if +5V-POD
does not start up due to a local defect, then +12V will not
be available as well. +5V-ON supply is enabled by the ONMODE signal (coming also from the standby
microprocessor) and is coming up a little bit later (20 ms)
due to the slower rise time needed to charge the USB
decoupling capacitor 2N31. +1V2 supply starts-up when
+12V appears, then at least 100 ms later, +1V8, +2V5 and
+3V3 will be activated via the ENABLE-3V3 signal from the
standby microprocessor. If +12V value is less than 10 V
then the last enumerated voltages will not show-up due to
the under-voltage detection circuit 6U10 + 7U10 and
surrounding components. Furthermore, if +12V is less than
8V then also +1V2 will not be available. The third DC-DC
convertor that delivers +1V4 out of +12V is started up when
the ENABLE-1V2 becomes active (low) and +12V is
present. The +Vtun generator (present only for the
analogue version of China platforms) will generate +33V
for the analogue tuner as soon as the 12V/3.3V DC-DC
converter will start to operate.
•The consumption of controller IC 7U00 is around 19 mA
(that means almost 200 mV drop voltage across resistor
3U01) and the consumption of controller IC 7U64 is around
12 mA.
•The current capability of DC-DC converters is quite high
(short-circuit current is 7 to 10 A), therefore if there is a
linear integrated stabiliser that, for example, delivers 1.8V
from +3V3 with its output overloaded, the +3V3 stays
usually at its normal value even though the consumption
from +3V3 increases significantly.
•The +1V8 and +2V5 supply voltages are obtained via linear
stabilizer made with discrete components that can deliver
a lot of current, therefore in case +1V8 or +2V5 are shortcircuited to GND then +3V3 will not have the normal value
but much less.
•The SUPPLY-FAULT signal (active low) is an internal
protection (error 9) of the DC-DC convertor and will occur
if the output voltage of any DC-DC convertor is out of limits
(10% of the normal value).
Fault Finding
•Symptom: +1V2 not present (even for a short while
~10 ms)
1. Check 12 V availability (resistor 3U01, MOS-FETs
7U03 and 7U08), value of +12 V, +12 V switch (7U14
+ 7U16 and surrounding components) and +5V-POD.
2. Check the voltage on pin 9 (1.5 V),
3. Check for +1V2 output voltage short-circuit to GND that
can generate pulsed over-currents 7...10 A through coil
5U02.
4. Check the over-current detection circuit (2U20 or 3U40
interrupted).
•Symptom: +1V4 not present (even for a short while
~10ms) while +12V is okay (also across input capacitors
2U6S and 2U6R).
1. Check resistor 3U7B and power MOS-FETs 7U61-1/2
2. Check the voltage on pin 4 (4 V)
3. Check enable signal ENABLE-1V2 (active “low”)
4. Check for +1V4 output voltage short-circuit to GND that
can generate pulsed over-currents 7...10 A through coil
5U60
5. Check the over-current detection reference(2U65 +
3U7C) and the boot components (2U66 + 6U60).
•
Symptom: +1V2 present for about 100ms, +1V8, +2V5
and +3V3 not rising.
1. Check the ENABLE-3V3 signal (active “low”),
2. Check the voltage on pin 8 (1.5 V),
3. Check the under-voltage detection circuit (the voltage
on collector of transistor 7U10-1 should be less than
0.8 V),
4. Check for output voltages short-circuits to GND (+3V3,
+2V5 and +1V8) that can generate pulsed overcurrents 7...10 A through coil 5U01,
5. Check the over-current detection circuit (2U18 or 3U31
interrupted).
•Symptom: +1V2 OK, +2V5 and +3V3 present for about
100 ms. Possible cause: SUPPLY-FAULT line stays “low”
even though the +3V3 and +1V2 is available - the standby
microprocessor is detecting that and switching “off” all
supply voltages.
1. Check the drop voltage across resistor 3U01 or 3U7B
(they could be too high, meaning a defective controller
IC or MOS-FETs),
2. Check if the boost voltage on pin 4 of controller IC
7U00 is less than 14 V (should be 19 V),
3. Check if +1V2 or +3V3 are higher than their normal
values - that can be due to defective DC feedback of
the respective DC-DC convertor (ex. 3U47, 3U77,
3U7L, 3U7J or 3U70).
•Symptom: +1V2, +1V4, +1V8, +2V5 or +3V3 shows a high
level of ripple voltage (audible noise can come from the
filtering coils 5U01, 5U02 or 5U60). Possible cause:
instability of the frequency and/or duty cycle of a DC-DC
converter or stabilizer.
1. Check the resistor 3U32 and 3U7D, capacitors 2U17
and 2U19, input and output decoupling capacitors.
2. Check a.c. feedback circuits
(2U23+2U24+3U55+3U63 for +1V2,
2U6D+2U6E+2U6G+3U6A+3U7E for +1V4 and
2U07+2U08+3U17+3U24 for +3V3), compensation
capacitors 2U25, 2U34, 2U36, 2U37, 2U40, 2U43,
2U68 and 2U6B.
•Symptom: +1V2, +1V4, +2V5 and +3V3 ok, no +Vtun
(analogue sets only). Possiblecause: the “+VTUN
GENERATOR” circuit (7U24+7U26+surroundings
components) is defective: check transistor 7U24 (it has to
have gate voltage pulses of about 10 V amplitude and drain
voltage pulses of about 35 V amplitude) and surroundings
components. A high consumption (more than 6 mA) from
+Vtun voltage can cause also +Vtun voltage to be too low
or zero.
Note: when a pair of power MOSFETs(7U01+7U06,
7U03+7U08 or 7U61-1/2) becomes defective the controller IC
7U00 or 7U64 should be replaced as well.
Service Modes, Error Codes, and Fault Finding
5.8.5Exit “Factory Mode”
When an “F” is displayed in the screen's right corner, this
means that the set is in “Factory” mode, and it normally
happens after a new SSB has been mounted.
To exit this mode, push the “VOLUME minus” button on the
TV’s keyboard control for 5 seconds and restart the set.
5.8.6Sanken display supply
The 47" sets in this chassis come with a Sanken buy-in supply.
The result of a failing Sanken display supply, e.g. one of the
following voltages is missing: +400V, +12V or +24V, will lead to
protection (blinking error 63). The set is switched off.
When the primary circuit of the on-board platform supply fails,
there is a high possibility that the main fuse of the Sanken
display supply will break. In this case the Sanken display
supply must not be replaced completely, just replace the
Sanken main value fuse and repair the on-board platform
supply. For safety reasons, make sure to use the correct fuse
type.
5.8.7SSB service supply connector
Connector 1B40 can be used to apply external supply (+12V
and +5V). In this way you do not need mains supply for
troubleshooting on the SSB. e.g. component level repair.
EN 43Q528.1A LA5.
5.8.8Tuner
For access to the components located under the tuner itself,
you need to desolder the ground connections and bend the
tuner up. To maintain a good performing tuner you must make
a new ground connection to the SSB, for instance by use of a
wire.
Caution: In case you replace the tuner, always check the tuner
option!
5.8.9 UI over PCI bus
The UI is not integrated in the RGB signal but is sent from
PNX85xx to PNX5050 via the PCI bus. TXT and MHEG are
integrated in the RGB signal. So if you have TXT signal but no
UI, check the PCI bus.
EN 44Q528.1A LA5.
5.8.10 SSB Replacement
Follow the instructions in the flowchart in case you have to
exchange the SSB. See figure “SSB replacement flowchart”.

5.9Software Upgrading
5.9.1 Introduction
The set software and security keys are stored in a NANDFlash, which is connected to the PNX85xx via the PCI bus.
It is possible for the user to upgrade the main software via the
USB port. This allows replacement of a software image in a
stand alone set, without the need of an E-JTAG debugger. A
description on how to upgrade the main software can be found
in the DFU.
Important: When the NAND-Flash must be replaced, a new
SSB must be ordered, due to the presence of the security
keys!!! (copy protection keys, MAC address, ...).
Perform the following actions after SSB replacement:
1. Set the correct option codes (see sticker inside the TV).
2. Update the TV software (see the DFU for instructions).
3. Perform the alignments as described in chapter 8 (section
“Reset of Repaired SSB”).
4. Check in CSM if the HDMI keys are valid.

•Remark: the above does not mean that you can reprogram
your HDMI keys with the “UpgradeAll.upg” file from the one
zip file. This can only be done in a secure environment (e.g.
the factory).
•The “UpgradeAll.upg” file is only used in the factory.
•The “FlashUtils.upg” file is only used by service centra
which are allowed to do component level repair on the
SSB.
Automatic Software Upgrade
In “normal” conditions, so when there is no major problem with
the TV, the main software and the default software upgrade
application can be upgraded with the “AUTORUN.UPG” (FUS
part of the one-zip file: e.g. 3104 337 03801 _FUS _Q581E_
0.37.0.0_commercial.zip). This can also be done by the
consumers themselves, but they will have to get their software
from the commercial Philips website or via the Software Update
Assistant in the user menu (see DFU). The “autorun.upg” file
must be placed in the root of your USB stick.
How to upgrade:
1. Copy “AUTORUN.UPG” to the root of your USB stick.
2. Insert USB stick in the side I/O while the set is in ON
MODE. The set will restart and the upgrading will start
automatically. As soon as the programming is finished, you
will get the message that you can remove your USB stick
and restart the set.
In case that you have started the download application
manually, the “autorun.upg” will maybe not be recognized.
What to do in this case:
1. Create a directory “UPGRADES” on your USB stick.
2. Rename the “autorun.upg” to something else, e.g. to
“software.upg”. Do not use long or complicated names,
keep it simple. Make sure that “AUTORUN.UPG” is no
longer present in the root of your USB stick.
3. Copy the renamed “upg” file into this directory.
4. Insert USB stick in the side I/O.
5. The renamed “upg” file will be visible and selectable in the
upgrade application.
Back-up Software Upgrade Application
If the default software upgrade application does not start (could
be due to a corrupted boot 2 sector) via the above described
method, you can try to activate the “back-up software upgrade
application”.
How to start the “back-up software upgrade application”
manually:
1. Disconnect the TV from the Mains/AC Power.
2. Press the “CURSOR DOWN” button on a Philips DVD RC6 remote control (it is also possible to use the TV remote in
“DVD” mode). Keep the “cursor down” button pressed
while reconnecting the TV to the Mains/AC Power.
3. The software upgrade application will start.
Manual Software Upgrade
In case that the software upgrade application does not start
automatically, you can also start it manually.
How to start the software upgrade application manually:
1. Disconnect the TV from the Mains/AC Power.
2. Press the “OK” button on a Philips DVD RC-6 remote
control (it is also possible to use the TV remote in “DVD”
mode). Keep the “OK” button pressed while reconnecting
the TV to the Mains/AC Power.
3. The software upgrade application will start.

5.9.3Stand-by Software Upgrade
There are two methods now to upgrade stand-by software:
Upgrade via USB
In this chassis it is possible to upgrade the Stand-by software
via a USB stick. The method is similar to upgrading the main
software via USB.
Use the following steps:
1. Create a directory “UPGRADES” on your USB stick.
2. Copy the Stand-by software (part of the one-zip file, e.g.
StandbySW_CFT01_9.0.0.0.upg) into this directory.
3. Insert the USB stick into the TV.
4. Start the download application manually (see paragraph
“Manual start of the Software Upgrade Application”.
5. Select the appropriate file and press the “red” button to
upgrade.
Upgrade via PC and ComPair interface
It will be possible to upgrade the Stand-by software via a PC
and the ComPair interface. Check paragraph “ComPair” on
how to connect the interface. To upgrade the Stand-by
software, use the following steps:
1. Disconnect the TV from the Mains/AC Power.
2. Short circuit the SPI pins [2] on the SSB (see figure
“Service mode pads” earlier in this chapter).
3. Keep the SPI pins shortened while connecting the TV to
the Mains/AC Power.
4. Release the short circuit after approx. two seconds.
5. Start up HyperTerminal (can be found in every Windows
application via Programs -> Accessories ->
Communications -> HyperTerminal). Use the following
settings:
–COM1
– Bits per second = 38400 (9600)*
– Data bits = 8
– Parity = none
– Stop bits = 1
– Flow control = None
6. Press “Shift U” on your PC keyboard. You should now see
the following info:
– PNX2015 Loader V1.0
– 19-09-2003
– DEVID=0x05
–Erasing
– MCSUM=0x0000
–=
7. If you do not see the above info, restart the above
procedure, and check your HyperTerminal settings and the
connections between PC and TV.
8. Via “Transfer” -> “Send text file ...”, you can send the
proper upgrade file to the TV (e.g. *.hex).
9. After successful programming, you must see the following
info (this can take several minutes!):
– DCSUM=0xC67E
–:Ok
– MCSUM=0xC67E
– Programming
– PCSUM=0xC67E
– Finished
10. If you do not see this info, restart the complete procedure.
11. Close HyperTerminal.
12. Disconnect and connect Mains/AC Power again.
(*) When having problems with upgrading, use the values
between brackets.
